RODOLPHE OLAUGHTON, OF W'ASHINGTON, DISTRICT OF COLUMBIA.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 550,041, dated November19, 1895.

Application filed July 18, 1895. Serial No. 556,388. (No model.)

To all whom it may concern:

Be it known that I, RoDoLIIE CLAUGHTON, a citizen of the United States,residing at W'ashingtomin the District of Columbia,have invented certainnew and useful Improvements in Transom-Lifters, of which the followingis a specification.

My invention relates to transom-operating devices; and it consists incombining with the transom and a pinion connected with the trunnionthereof a sliding-rod and rack and means for operating the same arrangedbeneath the trimming of the door, as fully set forth hereinafter, and asillustrated in the accompanying drawings, in which Figure 1 is anelevation of the door in part section, showing my improvedtransom-operating device. Fig. 2 is a sectional View 011 the line 2 2,Fig. 1. Fig. 3 is a view illustrating a modification.

The framing A of the door X is provided with a recess for receiving asliding rod 0, which has a rack e, which engages a pinion d upon thetrunnion a of the transom B. This trunnion may be connected with thetransom in any suitable manner, but as shown it projects at right anglesfrom a plate 5, which may be secured by screws to the edge of thetransom. As shown, the pinion d and the rod C are contained within therecess which is covered by the trimming around the door, so that none ofthese parts are exposed, and by moving the rod 0 upward or downward thepinion is rotated, carrying with it the transom, which is thus opened orclosed or set at any desired inclined position.

Any suitable means may be employed for imparting the sliding verticalmovement to the rod 0. Preferably the rod is provided near its lower endwith a rack f, with which engages an operating pinion or wheelD. Thiswheel may be a toothed wheel, as shown in Figs. 1 and 2, supported byabracket E, with the shaft 9 of the wheel extending outward and providedwith a handle in the shape of a key h, which may be turned to impartrotation to the pinion. Another form of operating-wheel is shown in Fig.3, where the wheel is in the form of a disk with a wormor spiral flanges at the inside engaging the rack f. The advantage of the latterconstruction is that the operating worm or spiral wheel will not onlyraise and lower the rod 0, but will serve to hold it in any position towhich it is set, so that the transom is locked in place in whateverposition it may be adjusted.

Without limiting myself to the precise construction and arrangement ofparts shown, I claim as my invention- 1. The combination with thetransom of a door, of a trunnion extending centrally from the side ofthe transom, a pinion d on the said trunnion, a sliding rod C providedwith a rack engaging the said pinion, and means for raising and loweringthe rod, the said rod and pinion arranged within a recess beneath thetrimming of the door, substantially as and for the purpose set forth.

2. The combination of the transom, trunnion, pinion d, sliding rod 0provided with a rack engaging the pinion, and with a rack f at the lowerend, a worm-wheel engaging the rack f, the pinion, worm-wheel and rodarranged within a recess beneath the trimming of the door, a shaft oraxis of the worm-wheel extending beyond said trimming, and a handle hupon the end of the said shaft, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
